An infant-led approach to complementary feeding is positively associated with language development

Development and validation of the baby eating behaviour coding system (BEBECS) to assess eating behaviour during complementary feeding

Eating behaviour in children is a matter of study for which diverse tools have been designed. Coding systems for videotaped meals allow the extraction of detailed in vivo information; however, there is no tool available for infants following a Baby-Led Weaning (BLW) method. This study aimed to create and validate a new tool to assess eating behaviour in infants during weaning, applicable regardless of the complementary feeding method. The Baby Eating Behaviour Coding System (BEBECS) was developed comprising time variables, behaviours, feeder-led actions, and other meal-related variables. Sixty videos of infants aged 6-18 months following spoon-feeding (SF) or BLW methods were coded by two trained coders. These scores were analysed together with intake and maternal ratings of liking and calmness. Additionally, combined analysis and internal comparison assessed the possible differences in BEBECS variables between SF and BLW. Inter-rater and test-retest reliability had good to excellent agreement: Cohen's Kappa >0.75, Lin's CCC >0.70, and Intraclass Correlation Coefficient >0.75, for almost all variables. Infants' liking and intake of the offered food correlated positively with meal duration and total count of mouth approaches but negatively with having leftovers and time between mouth approaches. Infants' calmness and tiredness were negatively correlated. More food than initially offered was available during the meal in BLW but not in SF. There was a tendency towards more autonomous behaviour in BLW infants regarding changes observed in the time the food was in the mouth at each stage (6, 12, and 18 months). In conclusion, BEBECS has the potential to be a valid tool for application in the research of infant eating behaviour during weaning by trained coders.

COVID-19 vaccine coverage, determinants and inequity amongst refugees and migrants in Pakistan: a cross-sectional study

OBJECTIVE

Migrants and refugees are at a disadvantage in accessing basic necessities. The objective of this study is to assess the inequity in access, needs and determinants of COVID-19 vaccination among refugees and migrant populations in Pakistan.

DESIGN

We conducted a mixed-method study comprising a cross-sectional survey and a qualitative study. In this paper, we will only report the findings from the cross-sectional survey.

SETTING

This survey was conducted in different cities of Pakistan including Quetta, Karachi and Hyderabad.

PARTICIPANTS

A total of 570 participants were surveyed including refugees and migrants, both in regular and irregular situations.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome of the study was to estimate the proportion of refugees and migrants, both in regular and irregular situations vaccinated against COVID-19 and assess the inequity. The χ2 test and Fisher's exact test were used to determine the significant differences in proportions between refugees and migrants and between regions.

RESULTS

The survey showed that only 26.9% of the refugee and migrant population were tested for COVID-19, 4.56% contracted coronavirus, and 3.85% were hospitalised due to COVID-19. About 66% of the refugees and migrants were fully vaccinated including those who received the single-dose vaccine or received all two doses, and 17.6% were partially vaccinated. Despite vaccination campaigns by the government, 14.4% of the refugee and migrant population remained unvaccinated mostly because of vaccines not being offered, distant vaccination sites, limited access, unavailability of COVID-19 vaccine or due to a difficult registration process. Vaccination rates varied across provinces, genders and migrant populations due to misconceptions, and several social, cultural and geographical barriers.

CONCLUSION

This study highlights the COVID-19 vaccine coverage, access and inequity faced by refugees and migrants during the pandemic. It suggests early prioritisation of policies inclusive of all refugees and migrants and the provision of identification documents to ease access to basic necessities.

Structural models of genome-wide covariance identify multiple common dimensions in autism

Common genetic variation has been associated with multiple phenotypic features in Autism Spectrum Disorder (ASD). However, our knowledge of shared genetic factor structures contributing to this highly heterogeneous phenotypic spectrum is limited. Here, we developed and implemented a structural equation modelling framework to directly model genomic covariance across core and non-core ASD phenotypes, studying autistic individuals of European descent with a case-only design. We identified three independent genetic factors most strongly linked to language performance, behaviour and developmental motor delay, respectively, studying an autism community sample (N = 5331). The three-factorial structure was largely confirmed in independent ASD-simplex families (N = 1946), although we uncovered, in addition, simplex-specific genetic overlap between behaviour and language phenotypes. Multivariate models across cohorts revealed novel associations, including links between language and early mastering of self-feeding. Thus, the common genetic architecture in ASD is multi-dimensional with overarching genetic factors contributing, in combination with ascertainment-specific patterns, to phenotypic heterogeneity.

Professional Feeding Guidance Improved Infants' Self-Feeding Proportion during Complementary Foods Introduction in Beijing, China: An Exploratory Study

An exploratory study was undertaken to examine the prevalence of infants' feeding patterns in Beijing, China, as well as the factors linked to infants' self-feeding proportion during the introduction of complementary foods, and the impact of professional feeding guidance on this proportion. A total of 122 families with infants aged 6-11 months from Beijing were included in the study. A descriptive analysis was employed to assess the prevalence of infants' feeding patterns, while generalized linear model analysis was utilized to investigate the factors associated with these patterns. All families were provided with comprehensive and personalized professional guidance regarding the introduction of complementary foods for infants. However, 64 families were lost to follow-up, leaving 58 families who were re-evaluated and queried after one month. To exclude the influence of infants aging, both the 64 families prior to receiving feeding guidance, and the 58 families after receiving feeding guidance, were included in the analysis. The families with infants aged 6-8 months and 9-11 months were compared separately based on the presence or absence of feeding guidance. Statistical tests, including the Wilcoxon rank-sum test and χ2 test, were conducted to assess any significant differences. The study revealed that the proportion of infants engaging in self-feeding was found to be remarkably low (10% [0%, 40%]). Furthermore, a significant positive association was observed between the proportion of infants engaging in self-feeding and their age (p < 0.001). Notably, after receiving professional feeding guidance, the proportion of infants engaging in self-feeding significantly increased (from 1% [0%, 20%] to 30% [10%, 50%], p < 0.001 for infants aged 6-8 months; from 20% [10%, 50%] to 40% [30%, 50%], p < 0.001 for infants aged 9-11 months). These findings contribute valuable insights for improving postnatal care practices during the introduction of complementary foods for infants.

Are Complementary Feeding Practices Aligned with Current Recommendations? A Narrative Review

The complementary feeding introduction period (introduction of solid foods alongside breastmilk or formula) is defining in children's health; however, it appears that many parents do not follow complementary feeding guidelines. Our aim was to describe current parental feeding practices during complementary feeding in relation to current recommendations and explore determinants of adherence to guidelines. We included any relevant studies published within the last decade in French or English and summarized findings by recommendation category. The timing of complementary food introduction varied widely across and within continents (earlier in North America and often delayed in Asia). The introduction of allergenic foods tended to be delayed globally. Although some parents now begin complementary feeding with solid foods (i.e., baby-led weaning), delayed introduction of lumpy textures was still prevalent in the United States and in Europe. The consumption of iron-rich foods was predominantly low in Africa. Added sugars were globally introduced early, especially in America. Evidence for the prevalence of responsive feeding practices among parents is unclear due to the small number of studies. Determinants of complementary feeding practices included parental characteristics, such as age, education, socio-economic status, and race/ethnicity. Interventions aiming to increase adherence to complementary feeding guidelines must account for parental characteristics.

What Has Changed over Years on Complementary Feeding in Italy: An Update

Current practice regarding complementary feeding (CF) is influenced by socio-cultural background. Our group already investigated the Italian approach to CF in the years 2015-2017. Our aim was to update those data by finding out: if the habits have changed nationwide, how the trends changed in each area, and if the differences between regions still exist. We devised and submitted to Italian primary care paediatricians (PCP) a questionnaire consisting of four items regarding the suggestions they gave to families about CF and compared the results to the ones from our previous survey. We collected 595 responses. Traditional weaning was the most recommended method, with a significant reduction compared to the period of 2015-2017 (41% vs. 60%); conversely, the proportion of PCP endorsing baby-led weaning (BLW) or traditional spoon-feeding with adult food tastings has increased, while the endorsement of commercial baby foods dropped. BLW is still more popular in the North and Centre compared to the South (24.9%, 22.3%, and 16.7%, respectively). The age to start CF and the habit of giving written information have not changed over time. Our results highlighted that Italian paediatricians encourage BLW and traditional CF with adult tastings more than in the past, at the expense of traditional spoon-feeding.

"The Kale Is Green" and Other Things Caregivers Say when Feeding Infants and Toddlers Are Associated with Child Rate of Acceptance

BACKGROUND

Responsive feeding is important for helping children to develop healthy eating behaviors. Verbal feeding interactions between caregivers and children may reflect caregiver's responsiveness and contribute to children's developing lexical networks related to food and eating.

OBJECTIVES

This project aimed to: 1) characterize what caregivers say to infants and toddlers during a single feeding session and 2) test the associations between caregiver's verbal prompts and food acceptance by children.

METHODS

Filmed interactions of caregivers and their infants (N = 46 infants aged 6-11 mo) and toddlers (N = 60 toddlers aged 12-24 mo) were coded and analyzed to explore the following: 1) what caregivers said during a single feeding session and 2) whether caregiver's verbalizations were associated with child food acceptance. Caregiver verbal prompts were coded during each food offer and summed across the feeding session; prompts were categorized as supportive, engaging, and unsupportive. Outcomes included accepted tastes, rejected tastes, and rate of acceptance. Mann-Whitney's U tests and Spearman's correlations tested bivariate associations. Multilevel ordered logistic regression tested associations between verbal prompt categories and the rate of acceptance across offers.

RESULTS

Verbal prompts were largely supportive (41%) and engaging (46%), and caregivers of toddlers used significantly more verbal prompts than caregivers of infants (mean ± SD: 34.5 ± 16.9 compared with 25.2 ± 11.6; P = 0.006). Among toddlers, more engaging and unsupportive prompts were associated with a lower rate of acceptance (ρ = -0.30, P = 0.02; ρ = -0.37, P = 0.004). For all children, multilevel analyses revealed that more unsupportive verbal prompts were associated with a lower rate of acceptance (b = -1.52; SE = 0.62; P = 0.01) and individual caregiver use of more engaging and unsupportive prompts than usual was associated with a lower rate of acceptance (b = -0.33; SE = 0.08; P < 0.001: b = -0.58; SE = 0.11; P < 0.001).

CONCLUSIONS

These findings suggest that caregivers may strive for a supportive and engaging emotional setting during feeding, although verbalization category may change as children exhibit more rejection. Furthermore, what caregivers say may change as children develop more advanced language capabilities.

Acceptance of a Novel Food is Related to Caregiver Perceptions of Infant and Toddler Food-related Receptive Language

OBJECTIVE

Language development, both what is understood (receptive language) and spoken (expressive language), is considered critical to a child's ability to understand and interact with their environment. However, little research has investigated the role children's early language skills might play in their food acceptance. The objective of this study was to explore the relationships between young children's food-related receptive language (FRL) and food-related expressive language (FEL) and acceptance of novel food.

METHODS

Caregivers (n = 54) reported their perceptions of children's (aged 7-24 months) FRL and FEL using the MacArthur-Bates Communicative Development Inventory. Novel food acceptance was observed (grams consumed) during a laboratory visit. Multivariable linear regression tested associations between FRL, FEL, and novel food acceptance, by child age (infants [aged from 7 to < 12 months], toddlers [aged 12-24 months]), and at a significance level of P < 0.1 for hypothesis-generating research.

RESULTS

Children's FRL and food acceptance differed by age (F = 8.08, P = 0.01). Among toddlers, greater FRL was associated with greater novel food acceptance (0.22 g [95% confidence interval, -0.04 to 0.49]), P = 0.09). In infants, greater FRL was associated with lower novel food acceptance (-0.80 g [95% confidence interval, -1.53 to -0.07], P = 0.03). No association between FEL and novel food acceptance was noted in either group.

CONCLUSIONS AND IMPLICATIONS

Toddlers' understanding of food-related vocabulary may facilitate food acceptance; however, young infants may not yet have sufficient FRL to facilitate novel food acceptance.
